Amphenol ICC 76350-114-72 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76350-114-72 is a through-hole, right-angle rectangular connector header with 72 positions at 0.100" (2.54mm) pitch, part of the BERGSTIK® series. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part features male pins with gold-plated mating contacts, phosphor bronze contact material, and thermoplastic insulation rated UL94 V-0. Substitute parts maintain functional compatibility while offering active product status and improved compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: connector type (header), contact type (male pin), number of positions (72), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (through hole, right angle), termination method (solder), fastening type (push-pull), contact shape (square), and insulation color (black). All substitute parts listed maintain these core specifications.

The substitute parts are grouped into two categories:

Direct Amphenol ICC Equivalent: 76350-114-72LF differs from the main part only in RoHS compliance status (RoHS Compliant vs. non-compliant) and product status (Active vs. Obsolete), with identical electrical and mechanical specifications.

Cross-Manufacturer Substitutes: Parts from Würth Elektronik (61307221021) and Samtec Inc. (TSW-136 series variants) provide functional equivalence with variations in contact finish specifications, insulation material composition, and operating temperature ranges. These parts maintain the same mating pitch, position count, mounting configuration, and termination method.

Engineering Selection Recommendations

For RoHS Compliance Requirements: Select 76350-114-72LF as the primary substitute. This part maintains identical mechanical and electrical specifications to the original 76350-114-72 while providing RoHS Compliant certification and active product status. This represents the lowest-risk substitution path for existing designs.

For Extended Temperature Range Applications: The Samtec TSW-136 series (TSW-136-08-G-D-RA, TSW-136-08-L-D-RA, TSW-136-08-S-D-RA, TSW-136-08-T-D-RA) offers operating temperature ranges of -55°C to 125°C, compared to the Würth Elektronik 61307221021 range of -40°C to 105°C. All Samtec variants provide ROHS3 Compliant certification and active product status.

For Specified Electrical Ratings: The Würth Elektronik 61307221021 provides explicit current rating (3A) and voltage rating (250V) specifications. This part is suitable for applications requiring documented electrical performance parameters.

Contact Finish Considerations: The original 76350-114-72 specifies gold mating contact finish with GXT™ plating. The 76350-114-72LF maintains this specification. Samtec TSW-136-08-G-D-RA and TSW-136-08-S-D-RA provide gold mating finishes, while TSW-136-08-L-D-RA and TSW-136-08-T-D-RA feature tin mating finishes. The Würth Elektronik 61307221021 provides gold mating finish without specified thickness.

Post Contact Length Variations: The original part specifies 0.305" (7.75mm) post length. Substitute parts feature shorter post lengths: Würth Elektronik at 0.118" (3.00mm) and Samtec variants at 0.090" (2.29mm). PCB design modifications may be required to accommodate these dimensional differences.

Frequently Asked Questions (FAQ)

Q: Can 76350-114-72LF be used as a direct replacement for 76350-114-72?

A: Yes. The 76350-114-72LF maintains identical connector type, position count, pitch, mounting configuration, and contact specifications. The primary differences are RoHS compliance status (Compliant vs. non-compliant) and product status (Active vs. Obsolete). No design modifications are required.

Q: What are the key differences between Amphenol ICC and Samtec substitute parts?

A: Amphenol ICC parts (76350-114-72 and 76350-114-72LF) feature longer post contact length (0.305"/7.75mm) and thermoplastic insulation. Samtec TSW-136 variants feature shorter post contact length (0.090"/2.29mm) and polybutylene terephthalate (PBT) insulation. Samtec parts offer extended operating temperature range (-55°C to 125°C) and ROHS3 compliance. PCB design modifications are necessary when switching from Amphenol to Samtec due to post length differences.

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

A: The Samtec TSW-136 series variants (TSW-136-08-G-D-RA, TSW-136-08-L-D-RA, TSW-136-08-S-D-RA) provide the widest operating temperature range of -55°C to 125°C. The TSW-136-08-T-D-RA variant operates from -55°C to 105°C. The Würth Elektronik 61307221021 operates from -40°C to 105°C.

Q: Are there contact finish differences between substitute parts?

A: Yes. The original 76350-114-72 and its direct equivalent 76350-114-72LF specify gold mating contact finish with GXT™ plating at 30.0µin (0.76µm) thickness. Samtec TSW-136-08-G-D-RA and TSW-136-08-S-D-RA provide gold mating finishes (10.0µin and 30.0µin thickness respectively). Samtec TSW-136-08-L-D-RA and TSW-136-08-T-D-RA feature tin mating finishes. The Würth Elektronik 61307221021 provides gold mating finish without specified thickness.

Q: What packaging options are available?

A: The original 76350-114-72 is supplied in unspecified packaging. The 76350-114-72LF, Würth Elektronik 61307221021, and all Samtec TSW-136 variants are supplied in Bulk packaging.

Q: Do substitute parts require PCB design modifications?

A: The 76350-114-72LF requires no design modifications. Cross-manufacturer substitutes (Würth Elektronik and Samtec) feature different post contact lengths (0.118" and 0.090" respectively versus the original 0.305"), which may require PCB footprint adjustments. Insulation height variations (0.219" for Samtec versus 0.200" for Amphenol) should be verified against board clearance requirements.

Q: Which substitute part is recommended for new designs?

A: For new designs requiring RoHS compliance and active product status, the 76350-114-72LF is the recommended choice due to specification equivalence with the original part. For applications requiring extended temperature range or specific electrical ratings, evaluate the Samtec TSW-136 series or Würth Elektronik 61307221021 based on design requirements.
