Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 104656-1 are grouped based on strict electrical and mechanical parameter alignment within the rectangular connector category. Substitution eligibility is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (10)
• Number of rows (2)
• Pitch spacing (0.050" / 1.27mm)
• Row spacing (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Shrouding configuration (Shrouded - 4 Wall)
• Insulation material (Liquid Crystal Polymer)

Secondary Considerations:

• Packaging format (Tube, Tape & Reel)
• RoHS compliance status
• Contact finish specifications
• Operating temperature range
• Current rating capacity

Parts listed as substitutes maintain compatibility with the 104656-1 within these defined parameters. Variations in contact finish thickness, contact shape geometry, insulation height, and mated stacking heights represent acceptable engineering tolerances for board-to-board connector applications.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5-104656-1

The 5-104656-1 is a direct variant of the 104656-1 from the same manufacturer. This part maintains identical electrical and mechanical specifications while offering ROHS3 compliance and Tube packaging. The primary distinction is the contact finish post material, which is Tin instead of Tin-Lead, and improved regulatory compliance status. This part is suitable for applications requiring RoHS compliance and is available in higher inventory quantities (3162 units).

Samtec TFM-105-12-S-D-LC

The TFM-105-12-S-D-LC is a Samtec Tiger Eye™ TFM series connector offering enhanced electrical performance with 2.9A per contact current rating and 275VAC voltage rating compared to the 104656-1. This part features an extended operating temperature range (-55°C ~ 125°C) and Board Lock fastening feature. The contact shape is square rather than circular, and insulation height is slightly reduced (0.290" vs 0.298"). This part is ROHS3 compliant and available in Tube packaging with 3300 units in stock.

Samtec TFM-105-12-S-D-A

The TFM-105-12-S-D-A provides equivalent functionality to the TFM-105-12-S-D-LC with identical electrical ratings and operating temperature range. This variant features Board Guide fastening instead of Board Lock. ROHS3 compliant with 2506 units available in Tube packaging.

Samtec TFM-105-12-S-D-A-K-TR

The TFM-105-12-S-D-A-K-TR is functionally equivalent to the TFM-105-12-S-D-A with the addition of Pick and Place feature designation and Tape & Reel packaging format. This configuration is optimized for automated assembly processes. ROHS3 compliant with 1302 units in stock.

Samtec TFM-105-12-L-D-A

The TFM-105-12-L-D-A represents a variant within the Samtec Tiger Eye™ TFM series with identical core specifications to other TFM variants. This part features Board Guide fastening and is available in Tube packaging with 869 units in inventory. ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can the 5-104656-1 be used as a direct replacement for the 104656-1?

A: Yes. The 5-104656-1 maintains identical connector type, position count, pitch spacing, mounting type, termination method, and fastening configuration. The primary differences are packaging format (Tube vs. unspecified) and RoHS compliance status. The contact finish post material differs (Tin vs. Tin-Lead), which is acceptable for board-to-board solder termination applications.

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

A: TE Connectivity parts (104656-1 and 5-104656-1) maintain the original 0.5A per contact current rating and circular contact shape. Samtec TFM series parts provide enhanced electrical performance with 2.9A per contact current rating and 275VAC voltage rating, extended operating temperature range (-55°C ~ 125°C vs. -65°C ~ 105°C), and square contact geometry. All parts share identical pitch spacing, row configuration, and shrouding specifications.

Q: Are Samtec TFM parts backward compatible with the 104656-1?

A: Samtec TFM parts are mechanically and electrically compatible for board-to-board applications within the defined pitch and position parameters. However, the enhanced current rating (2.9A vs. 0.5A) and voltage rating (275VAC) represent performance improvements rather than direct equivalence. Contact geometry differs (square vs. circular), which may affect mating force characteristics and connector feel during engagement.

Q: What packaging options are available?

A: The 104656-1 is available in unspecified packaging. The 5-104656-1 is supplied in Tube packaging. Samtec TFM variants are available in Tube packaging (TFM-105-12-L-D-A, TFM-105-12-S-D-A, TFM-105-12-S-D-LC) or Tape & Reel format (TFM-105-12-S-D-A-K-TR). Tape & Reel packaging is optimized for automated pick-and-place assembly processes.

Q: Which substitute part offers the best RoHS compliance?

A: All substitute parts listed (5-104656-1 and all Samtec TFM variants) are ROHS3 compliant. The original 104656-1 is RoHS non-compliant. For applications requiring RoHS compliance, the 5-104656-1 provides the closest functional match with improved regulatory status.

Q: What is the difference between TFM-105-12-S-D-A and TFM-105-12-S-D-LC?

A: Both parts are functionally equivalent with identical electrical ratings, operating temperature range, and current capacity. The primary difference is the fastening feature: TFM-105-12-S-D-A includes Board Guide fastening, while TFM-105-12-S-D-LC includes Board Lock fastening. Board Lock provides positive mechanical retention, while Board Guide offers alignment guidance during mating.

Q: Can Samtec TFM parts be used in applications originally designed for the 104656-1?

A: Yes, within the constraints of the application design. Samtec TFM parts maintain the critical mechanical parameters (pitch, position count, mounting type, shrouding) required for board-to-board connectivity. The enhanced electrical ratings (2.9A per contact, 275VAC) provide performance margin for applications originally rated at 0.5A. The extended operating temperature range (-55°C ~ 125°C) accommodates broader environmental conditions. Physical dimensions vary slightly (insulation height, contact length), which should be verified against PCB layout constraints.

Q: What is the inventory status for each substitute part?

A: Current inventory levels are as follows: 104656-1 (693 units), 5-104656-1 (3162 units), TFM-105-12-L-D-A (869 units), TFM-105-12-S-D-A (2506 units), TFM-105-12-S-D-A-K-TR (1302 units), TFM-105-12-S-D-LC (3300 units). The 5-104656-1 and TFM-105-12-S-D-LC offer the highest availability.
