Engineering Selection Recommendations

All listed substitute parts satisfy the core mechanical and electrical requirements for direct replacement of the Amphenol ICC 76350-103-72. Selection among active alternatives should be based on the following factors:

Compliance Status: All substitute parts carry ROHS3 compliance, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulations, any of the listed substitutes is appropriate.

Product Availability: The Würth Elektronik 61307221021, Preci-Dip 802-V3-072-20-001101, and all Samtec TSW variants are classified as active products with current manufacturing support and documented inventory availability.

Operating Temperature Range: The Würth Elektronik part operates from -40°C to 105°C. The Preci-Dip part and Samtec TSW-136-08-G-D-RA, TSW-136-08-L-D-RA, and TSW-136-08-S-D-RA variants operate from -55°C to 125°C. The Samtec TSW-136-08-T-D-RA operates from -55°C to 105°C. Selection should align with application temperature requirements.

Contact Finish Specifications: The original part features gold mating contact finish at 30.0µin thickness. Samtec TSW-136-08-G-D-RA provides gold mating finish at 10.0µin thickness. Samtec TSW-136-08-T-D-RA provides tin mating finish. Preci-Dip 802-V3-072-20-001101 provides gold mating finish at 29.5µin thickness, closely matching the original specification.

Electrical Ratings: The Würth Elektronik part is rated at 3A, 250V. The Preci-Dip part is rated at 3A, 150VDC. Samtec parts do not specify current or voltage ratings in the provided data. For applications requiring specific electrical performance, the Würth Elektronik or Preci-Dip options provide documented ratings.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 76350-103-72 be directly replaced with any of the listed substitutes?

A: Yes. All listed parts meet the critical substitution parameters: 72-position, 2-row header configuration at 0.100" (2.54mm) pitch, through-hole right-angle mounting, solder termination, push-pull fastening, and UL94 V-0 flammability rating. Physical and electrical compatibility is established.

Q: What is the primary reason for seeking substitutes for the 76350-103-72?

A: The original part is classified as obsolete. Active alternatives ensure continued supply chain access, manufacturing support, and compliance with current regulatory standards including ROHS3.

Q: Are there differences in contact material between the original and substitutes?

A: Yes. The original part uses phosphor bronze contacts. The Würth Elektronik part uses copper alloy. The Preci-Dip part uses brass. The Samtec parts use phosphor bronze. Contact material differences do not affect substitution eligibility when all other parameters align.

Q: Do all substitutes have the same insulation material?

A: No. The original part uses thermoplastic insulation. The Würth Elektronik part uses polyamide (PA6T), nylon 6T. The Preci-Dip part uses polycyclohexylenedimethylene terephthalate (PCT), polyester, glass filled. The Samtec parts use polybutylene terephthalate (PBT). Insulation material variations do not preclude substitution when core mechanical and electrical parameters are identical.

Q: Which substitute offers the closest match to the original contact finish specification?

A: The Preci-Dip 802-V3-072-20-001101 provides gold mating contact finish at 29.5µin thickness, closely matching the original 30.0µin specification. The Samtec TSW-136-08-G-D-RA provides gold finish at 10.0µin thickness, representing a thinner coating.

Q: What is the operating temperature range for each substitute?

A: Würth Elektronik 61307221021: -40°C to 105°C. Preci-Dip 802-V3-072-20-001101: -55°C to 125°C. Samtec TSW-136-08-G-D-RA, TSW-136-08-L-D-RA, TSW-136-08-S-D-RA: -55°C to 125°C. Samtec TSW-136-08-T-D-RA: -55°C to 105°C. Selection should align with application requirements.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitutes carry ROHS3 compliance. The original Amphenol ICC part is RoHS non-compliant. For applications subject to RoHS regulations, any substitute is appropriate.

Q: Do the Samtec TSW variants differ from each other?

A: The Samtec TSW variants differ in contact finish specifications. TSW-136-08-G-D-RA features gold mating and gold post finish. TSW-136-08-L-D-RA features gold mating and tin post finish. TSW-136-08-S-D-RA features gold mating at 30.0µin thickness and tin post finish. TSW-136-08-T-D-RA features tin mating and tin post finish. All variants maintain identical mechanical configuration and core electrical parameters.

Q: What is the moisture sensitivity level for the substitutes?

A: The Würth Elektronik part lists MSL as not applicable. The Preci-Dip and Samtec parts list MSL as 1 (unlimited), matching the original part specification.
