Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 104656-6 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 60
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• Termination: Solder
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0

Allowable Variations:

• Contact Shape: Circular (main part) to Square (substitute parts) - functionally compatible within connector geometry
• Contact Length - Mating: 0.120" (3.05mm) to 0.139" (3.53mm) - within acceptable mating depth tolerance
• Insulation Height: 0.298" (7.57mm) to 0.290" (7.37mm) - within acceptable tolerance
• Current Rating: 0.5A per Contact (main part) to 2.9A per Contact (substitute parts) - higher rating is backward compatible
• Operating Temperature: -65°C ~ 105°C (main part) to -55°C ~ 125°C (substitute parts) - extended range is backward compatible
• Contact Finish Thickness - Mating: 30.0µin (0.76µm) to 15.0µin (0.38µm) - both provide adequate contact durability
• Packaging: Tube to Tape & Reel - format variation only
• RoHS Status: Non-compliant (main part) to ROHS3 Compliant (substitute parts) - compliance upgrade

The three substitute parts listed (Samtec TFM-130-12-L-D-A-K-TR, TFM-130-12-S-D-A, and TFM-130-12-S-D-LC) meet all mandatory matching parameters and fall within allowable variations.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are classified as Active product status and are suitable for direct substitution of the TE Connectivity 104656-6 based on electrical and mechanical parameter equivalence.

Samtec TFM-130-12-L-D-A-K-TR is supplied in Tape & Reel packaging format and includes Pick and Place features. This variant is appropriate for high-volume automated assembly operations. The part is ROHS3 compliant and provides enhanced current rating (2.9A per Contact) and extended operating temperature range (-55°C ~ 125°C).

Samtec TFM-130-12-S-D-A is supplied in Tube packaging, matching the original part's packaging format. This variant includes Board Guide features and is ROHS3 compliant. The part provides enhanced current rating and extended operating temperature range. REACH status is listed as Unaffected.

Samtec TFM-130-12-S-D-LC is supplied in Tube packaging and includes Board Lock features, matching the fastening enhancement present in the original TE Connectivity part. This variant is ROHS3 compliant and provides enhanced current rating and extended operating temperature range. REACH status is listed as Unaffected.

All substitute parts meet UL94 V-0 flammability requirements and maintain Moisture Sensitivity Level 1 (Unlimited) classification. The Samtec parts provide improved RoHS compliance status compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can the Samtec TFM-130-12-L-D-A-K-TR be used as a direct replacement for the TE Connectivity 104656-6?

A: Yes. Both parts share identical mating pitch (0.050"), position count (60), row configuration (2 rows), connector type (Header), contact type (Male Pin), mounting type (Surface Mount), shrouding (Shrouded - 4 Wall), fastening type (Push-Pull), and termination method (Solder). The primary difference is packaging format (Tape & Reel versus Tube) and the inclusion of Pick and Place features in the Samtec variant.

Q: What is the difference between the three Samtec substitute options?

A: The three Samtec parts differ in packaging and mechanical features. TFM-130-12-L-D-A-K-TR is supplied in Tape & Reel format with Pick and Place features, suitable for automated assembly. TFM-130-12-S-D-A is supplied in Tube format with Board Guide features. TFM-130-12-S-D-LC is supplied in Tube format with Board Lock features, which matches the Board Lock feature of the original TE Connectivity part.

Q: Are there any electrical performance differences between the main part and the substitutes?

A: The substitute parts provide higher current rating (2.9A per Contact versus 0.5A per Contact) and extended operating temperature range (-55°C ~ 125°C versus -65°C ~ 105°C). These enhancements are backward compatible and do not affect substitution suitability. The Samtec parts also specify 275VAC voltage rating, which is not specified for the original part.

Q: Does the contact shape difference (Circular versus Square) affect compatibility?

A: No. The contact shape difference between the TE Connectivity part (Circular) and Samtec substitutes (Square) does not affect mating compatibility. Both shapes function within the same connector geometry and mating interface.

Q: What is the significance of the RoHS compliance difference?

A: The original TE Connectivity 104656-6 is RoHS non-compliant, while all three Samtec substitutes are ROHS3 compliant. This represents a compliance upgrade. If your application or supply chain requires RoHS compliance, the Samtec parts satisfy this requirement.

Q: Which substitute part should be selected for high-volume production?

A: The Samtec TFM-130-12-L-D-A-K-TR supplied in Tape & Reel format with Pick and Place features is optimized for high-volume automated assembly operations.

Q: Which substitute part should be selected if Board Lock features are required?

A: The Samtec TFM-130-12-S-D-LC includes Board Lock features, matching the fastening enhancement of the original TE Connectivity part. This variant is supplied in Tube packaging.

Q: Are the contact finish thickness variations significant?

A: The contact finish thickness variations (30.0µin to 15.0µin for mating surfaces) are within acceptable durability specifications for both the original and substitute parts. Both thicknesses provide adequate contact protection and signal integrity.

Q: What is the impact of the insulation height difference?

A: The insulation height difference (0.298" versus 0.290") is within acceptable tolerance and does not affect connector functionality or mating compatibility.
