Amphenol ICC 91036-140 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 91036-140 is a surface mount rectangular connector header with 80 positions arranged in 2 rows at 0.050" (1.27mm) pitch. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning. The Rib-Cage™ III series connector provides board-to-board connectivity with shrouded 4-wall construction and push-pull fastening for secure mating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91036-140 is determined by strict alignment with the following critical parameters: connector type (header), contact type (male pin), number of positions (80), number of rows (2), mating pitch (0.050" / 1.27mm), row spacing (0.050" / 1.27mm), mounting type (surface mount), style (board to board), shrouding (shrouded 4-wall), fastening type (push-pull), and material flammability rating (UL94 V-0).

Two substitute parts meet these criteria:

91036-140LF (Amphenol ICC) - Direct manufacturer variant with identical electrical and mechanical specifications. Primary difference is RoHS compliance status and contact finish post material (Tin vs. Tin-Lead).

104693-8 (TE Connectivity AMP Connectors) - Cross-manufacturer equivalent from the AMPMODU 50/50 Grid series. Maintains all critical mating parameters and board-to-board functionality. Differences include contact shape (circular vs. square), insulation material (LCP vs. thermoplastic glass-filled), current rating per contact (0.5A vs. 1A), and operating temperature range (-65°C ~ 105°C vs. -55°C ~ 130°C).

Parameter Comparison

Engineering Selection Recommendations

91036-140LF is the primary substitute for the obsolete 91036-140. Both parts are manufactured by Amphenol ICC within the Rib-Cage™ III series and maintain identical electrical and mechanical specifications. The 91036-140LF offers the advantage of active product status and RoHS compliance, addressing regulatory requirements for new designs. The contact finish post material change from Tin-Lead to Tin aligns with lead-free manufacturing standards.

104693-8 serves as a cross-manufacturer alternative from TE Connectivity. This part maintains all critical mating parameters and board-to-board connectivity requirements. However, the operating temperature range is reduced to -65°C ~ 105°C compared to the original -55°C ~ 130°C specification. The current rating per contact is 0.5A versus 1A on the original part. These differences require evaluation against specific application requirements. The TE Connectivity part offers RoHS compliance and active product status.

Selection between 91036-140LF and 104693-8 depends on application thermal requirements and current distribution across contacts. For applications operating above 105°C or requiring the full 1A current rating per contact, 91036-140LF is the appropriate choice. For general-purpose applications within the reduced temperature range, 104693-8 provides an alternative from an established connector manufacturer.

Frequently Asked Questions (FAQ)

Q: Can 91036-140LF be used as a direct replacement for 91036-140?

A: Yes. The 91036-140LF maintains identical electrical and mechanical specifications including pitch, number of positions, row spacing, mounting type, shrouding, and fastening type. The primary differences are product status (active vs. obsolete) and RoHS compliance.

Q: What are the key differences between 91036-140LF and 104693-8?

A: Both parts share identical mating pitch (0.050" / 1.27mm), number of positions (80), number of rows (2), and board-to-board style. Differences include: contact shape (square vs. circular), insulation material (thermoplastic glass-filled vs. LCP), operating temperature range (-55°C ~ 130°C vs. -65°C ~ 105°C), and current rating (1A vs. 0.5A per contact).

Q: Is the 104693-8 suitable for high-temperature applications?

A: The 104693-8 operates within -65°C ~ 105°C. Applications requiring operation above 105°C should use 91036-140LF, which supports -55°C ~ 130°C.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both 91036-140LF and 104693-8 are RoHS compliant. The original 91036-140 is RoHS non-compliant.

Q: What is the current handling capability difference between the substitutes?

A: The 91036-140LF maintains the original 1A current rating. The 104693-8 is rated at 0.5A per contact. For applications requiring full 1A current distribution, 91036-140LF is the appropriate selection.

Q: Do the substitute parts have the same packaging?

A: Both 91036-140LF and 104693-8 are supplied in tube packaging. The original 91036-140 packaging is not specified in the provided data.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts (91036-140, 91036-140LF, and 104693-8) have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
