Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1-104655-1 are grouped into two categories based on substitution logic:

Category 1: Direct TE Connectivity Substitutes The part 6-104655-1 is a direct substitute within the same manufacturer and series. This part maintains identical electrical and mechanical specifications with the exception of contact finish on the post (Tin versus Tin-Lead). Both parts share the same 100-position, 2-row configuration, 1.27mm pitch, surface mount termination, shrouded 4-wall design, and push-pull fastening. Operating temperature range, current rating, insulation material, and flammability rating are identical.

Category 2: Cross-Manufacturer Samtec Substitutes The Samtec Tiger Eye™ TFM and TFML series connectors provide functional equivalence with measurable parameter variations. These parts maintain the core specifications: 100 positions, 2 rows, 1.27mm pitch, surface mount solder termination, shrouded 4-wall design, and LCP insulation. Key differentiators include:

• Contact shape: Square (Samtec) versus Circular (TE Connectivity)
• Contact length - mating: 0.131" (3.33mm) for TFM series; 0.134" (3.39mm) for TFML series versus 0.120" (3.05mm) for 1-104655-1
• Insulation height: 0.220" (5.60mm) for Samtec versus 0.226" (5.74mm) for TE Connectivity
• Current rating: 2.9A per contact (Samtec) versus 0.5A per contact (TE Connectivity)
• Voltage rating: 275VAC (Samtec) versus unspecified (TE Connectivity)
• Operating temperature: -55°C to 125°C (Samtec) versus -65°C to 105°C (TE Connectivity)
• Fastening type: Push-Pull (TFM series) or Friction Lock (TFML series) versus Push-Pull (TE Connectivity)
• Features: Board Guide or Board Lock variants available

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and UL94 V-0 flammability classification.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (TE Connectivity 6-104655-1)

The 6-104655-1 is a direct substitute for the 1-104655-1 within the same manufacturer ecosystem. Both parts maintain identical mechanical and electrical specifications with the exception of post contact finish material (Tin versus Tin-Lead). Both parts carry active product status, ROHS3 compliance, and MSL 1 rating. Selection of 6-104655-1 is appropriate when inventory availability of the primary part is constrained or when lead time optimization is required. The parts are functionally interchangeable in all applications where the original 1-104655-1 is specified.

Cross-Manufacturer Substitution (Samtec Tiger Eye™ Series)

Samtec TFM and TFML series connectors provide functional equivalence with specific application considerations. These parts are suitable for substitution when:

1. The application circuit operates within the Samtec operating temperature range of -55°C to 125°C (narrower than the TE Connectivity -65°C to 105°C range)
2. The application can accommodate the increased current rating of 2.9A per contact (higher than the 0.5A rating of 1-104655-1)
3. The application can accommodate the increased voltage rating of 275VAC
4. The application can accommodate the square contact geometry and increased mating contact length (0.131" to 0.134" versus 0.120")
5. The application can accommodate the reduced insulation height (0.220" versus 0.226")

All Samtec substitutes maintain ROHS3 compliance, MSL 1 rating, and UL94 V-0 flammability classification.

Feature-Specific Selection

TFM-150-02-L-D-LC and TFM-150-02-S-D-LC incorporate Board Lock features, matching the mechanical retention approach of the original 1-104655-1. TFM-150-02-H-D-A, TFM-150-02-L-D-A, and TFM-150-02-S-D-A incorporate Board Guide features. TFML-150-02-S-D-A incorporates Board Guide features with Friction Lock fastening (distinct from Push-Pull). TFM-150-02-S-D provides no specified features.

Contact Finish Considerations

TFM-150-02-L-D-A and TFM-150-02-L-D-LC specify reduced gold plating thickness on mating contacts (15.0µin versus 30.0µin). All other Samtec variants maintain 30.0µin gold plating thickness matching the original part.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-104655-1 be used as a direct replacement for 1-104655-1?

A: Yes. The 6-104655-1 is a direct substitute with identical electrical and mechanical specifications. The only difference is the post contact finish material (Tin versus Tin-Lead). Both parts are ROHS3 compliant and maintain the same operating temperature range, current rating, and mechanical configuration.

Q: What are the key differences between TE Connectivity and Samtec substitutes?

A: The primary differences are contact shape (circular for TE Connectivity versus square for Samtec), mating contact length (0.120" for TE Connectivity versus 0.131" to 0.134" for Samtec), insulation height (0.226" versus 0.220"), current rating (0.5A versus 2.9A), voltage rating (unspecified versus 275VAC), and operating temperature range (-65°C to 105°C versus -55°C to 125°C). All parts maintain 100 positions, 2 rows, 1.27mm pitch, surface mount solder termination, and shrouded 4-wall design.

Q: Are Samtec TFM and TFML series connectors interchangeable with each other?

A: TFM and TFML series share the same 100-position, 2-row, 1.27mm pitch configuration and surface mount termination. The primary difference is fastening type: TFM series uses Push-Pull fastening, while TFML series uses Friction Lock fastening. Mating contact length also differs (0.131" for TFM versus 0.134" for TFML). Selection depends on the specific fastening mechanism required by the application.

Q: What is the significance of Board Lock versus Board Guide features?

A: Board Lock and Board Guide are mechanical retention features that affect how the connector interfaces with the PCB. The original 1-104655-1 incorporates Board Lock. Samtec substitutes offer both Board Lock variants (TFM-150-02-L-D-LC and TFM-150-02-S-D-LC) and Board Guide variants (TFM-150-02-H-D-A, TFM-150-02-L-D-A, and TFM-150-02-S-D-A). Selection should match the mechanical retention approach required by the application PCB design.

Q: Can Samtec connectors be used in applications with operating temperatures below -55°C?

A: No. Samtec TFM and TFML series connectors are rated for -55°C to 125°C operating temperature. Applications requiring operation below -55°C must use the TE Connectivity 1-104655-1 or 6-104655-1, which are rated for -65°C to 105°C.

Q: What is the impact of increased current rating in Samtec substitutes?

A: Samtec TFM series connectors are rated for 2.9A per contact, compared to 0.5A per contact for the TE Connectivity 1-104655-1. This higher rating provides additional current-carrying capacity. Applications designed for the lower 0.5A rating can safely use Samtec substitutes without current-related concerns. Applications requiring the full 2.9A capacity benefit from the Samtec design.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (TE Connectivity 6-104655-1 and all Samtec TFM and TFML variants) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and UL94 V-0 flammability classification.

Q: What is the difference between contact finish options in Samtec parts?

A: Samtec offers variants with different gold plating thicknesses on mating contacts. TFM-150-02-L-D-A and TFM-150-02-L-D-LC specify 15.0µin (0.38µm) gold plating, while other variants specify 30.0µin (0.76µm) gold plating, matching the original 1-104655-1. Contact finish thickness affects wear resistance and contact reliability over mating cycles.

Q: How do contact shape differences affect compatibility?

A: The original 1-104655-1 uses circular contacts, while Samtec TFM and TFML series use square contacts. Contact shape affects the contact interface geometry and mating force characteristics. Samtec square contacts provide different contact pressure distribution compared to circular contacts. Compatibility depends on the mating connector design and whether it is designed to accept square or circular contact geometry.

Q: What inventory levels are available for each substitute part?

A: Inventory availability varies: 1-104655-1 (1129 pcs), 6-104655-1 (2513 pcs), TFM-150-02-H-D-A (1018 pcs), TFM-150-02-L-D-A (1118 pcs), TFM-150-02-L-D-LC (1102 pcs), TFM-150-02-S-D (1240 pcs), TFM-150-02-S-D-A (783 pcs), TFM-150-02-S-D-LC (1571 pcs), and TFML-150-02-S-D-A (630 pcs). Inventory levels should be confirmed at time of procurement.
