Engineering Selection Recommendations

Amphenol ICC BERGSTIK® Series (55102-G17-05, 55102-G17-10): These parts maintain the same manufacturer lineage as the obsolete 76350-104-10 and share identical pitch, position count, and row spacing. Both are active products with current inventory availability. The 55102-G17-05 and 55102-G17-10 differ only in contact finish post composition (tin vs. unspecified in original). Insulation height is increased to 0.240" (6.10mm) compared to the original 0.200" (5.08mm). These parts remain RoHS non-compliant, matching the original part's regulatory status. Selection between these two variants depends on post-finish requirements for your application.

Harwin M20 Series (M20-9740542, M20-9740546): Both Harwin M20 variants are active products with ROHS3 compliance, providing regulatory advantage over the original part. Contact material differs (brass vs. phosphor bronze), and contact length specifications are marginally shorter (0.228" vs. 0.230" mating length). Operating temperature range extends to -40°C ~ 105°C with specified current rating of 3A per contact. The M20-9740542 features gold mating finish; M20-9740546 features tin mating finish. These parts are cuttable headers, offering design flexibility not present in the original part.

Samtec TSW Series (TSW-105-08-G-D-RA, TSW-105-08-L-D-RA, TSW-105-08-T-D-RA): All three Samtec TSW variants are active products with ROHS3 compliance. Contact material is phosphor bronze, matching the original part. Operating temperature range extends to -55°C ~ 125°C (TSW-105-08-G-D-RA and TSW-105-08-L-D-RA) or -55°C ~ 105°C (TSW-105-08-T-D-RA). Contact post length is reduced to 0.090" (2.29mm) compared to the original 0.120" (3.05mm). Mating contact finish options include gold (TSW-105-08-G-D-RA), gold with tin post (TSW-105-08-L-D-RA), or tin (TSW-105-08-T-D-RA). Insulation material is PBT, providing enhanced thermal and chemical resistance compared to the original thermoplastic specification.

Regulatory Compliance Consideration: If RoHS3 compliance is required for your application, select from the Harwin M20 series or Samtec TSW series. If RoHS non-compliance is acceptable or required to match legacy system specifications, the Amphenol ICC BERGSTIK® 55102 series maintains direct compatibility with the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 76350-104-10 with any of these substitute parts?

A: All listed substitute parts share the critical electrical and mechanical parameters required for functional compatibility: 0.100" (2.54mm) pitch, 10 positions in 2 rows, through-hole right-angle mounting, solder termination, and push-pull fastening. Direct mechanical and electrical substitution is supported. However, verify that secondary parameter variations (contact post length, insulation height, contact finish composition) do not conflict with your specific PCB layout or mating connector specifications.

Q: What is the difference between the Amphenol ICC 55102-G17-05 and 55102-G17-10?

A: Both parts are functionally identical in electrical and mechanical parameters. The designation difference reflects contact finish post composition: 55102-G17-05 specifies tin post finish, while 55102-G17-10 also specifies tin post finish. Both maintain gold mating surface finish (GXT™). Selection between these variants should be based on your application's solderability and post-finish requirements.

Q: Why do the Samtec TSW parts have shorter contact post length (0.090" vs. 0.120")?

A: Contact post length is a design parameter that affects insertion depth and mating force characteristics. The shorter TSW post length (0.090") is within acceptable tolerance for standard 0.100" (2.54mm) pitch connector applications and does not preclude functional substitution. Verify that your PCB pad depth and mating connector cavity depth accommodate this variation.

Q: Are the Harwin M20 cuttable headers compatible with fixed-position applications?

A: Yes. The cuttable feature of the M20 series allows post-manufacturing customization but does not prevent use in fixed 10-position configurations. The connector functions identically to non-cuttable headers when used in the full 10-position format.

Q: What is the significance of the insulation height variation between parts?

A: Insulation height affects the overall profile of the connector assembly. The original 76350-104-10 specifies 0.200" (5.08mm); the Amphenol ICC 55102 series specifies 0.240" (6.10mm); the Samtec TSW series specifies 0.219" (5.56mm). Verify that your PCB layout and enclosure clearances accommodate the selected part's insulation height to prevent mechanical interference.

Q: Which substitute part offers the widest operating temperature range?

A: The Samtec TSW-105-08-G-D-RA and TSW-105-08-L-D-RA offer the widest operating temperature range of -55°C ~ 125°C. The original 76350-104-10 does not specify an operating temperature range. If extended temperature performance is required, the Samtec TSW series is the appropriate selection.

Q: Do all substitute parts meet UL94 V-0 flammability requirements?

A: Yes. All substitute parts listed maintain UL94 V-0 material flammability rating, matching the original part's specification.

Q: What is the inventory status of these substitute parts?

A: All substitute parts are currently active products with confirmed inventory availability: 55102-G17-05 (1052 pcs), 55102-G17-10 (859 pcs), M20-9740542 (2908 pcs), M20-9740546 (2477 pcs), TSW-105-08-G-D-RA (2110 pcs), TSW-105-08-L-D-RA (2780 pcs), TSW-105-08-T-D-RA (1955 pcs).

Q: Which substitute part is most similar to the original 76350-104-10?

A: The Amphenol ICC 55102-G17-05 and 55102-G17-10 are the most similar, sharing the same manufacturer, series (BERGSTIK®), and contact material (phosphor bronze). These parts maintain the original part's RoHS non-compliant status and are direct lineage replacements within the Amphenol ICC product portfolio.
