M80-8910401 Equivalent & Substitute Parts

Part Overview

The M80-8910401 is a 4-position receptacle connector from Harwin Inc.'s Datamate L-Tek series, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch mating. This connector features through-hole solder termination, gold-plated mating contacts, and is rated for -55°C to 125°C operation with 120V voltage rating. The part is currently obsolete, making identification of active equivalent substitutes essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The M80-8500442 qualifies as a direct substitute for the M80-8910401 based on the following critical parameters:

Mechanical compatibility is established through identical connector type (receptacle), contact type (female socket), number of positions (4), mating pitch (0.079"/2.00mm), row configuration (2 rows with 0.079" spacing), mounting method (through hole), and fastening type (locking ramp). Both connectors maintain the same insulation height (0.202"/5.14mm) and mated stacking heights (7.23mm, 7.85mm).

Electrical compatibility is confirmed through matching contact material (beryllium copper), contact finish on mating surface (gold with 12.0µin/0.30µm thickness), and operating temperature range (-55°C ~ 125°C). Both parts carry UL94 V-0 flammability rating and identical ECCN and HTSUS classifications.

The primary differences are product status (M80-8500442 is active versus M80-8910401 obsolete), packaging (tube versus unspecified), voltage rating (800V versus 120V), contact post finish (tin versus tin-lead), insulation material (polyamide PA46 nylon 4/6 glass-filled versus polyester glass-filled), and RoHS compliance (ROHS3 compliant versus non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The M80-8500442 is the manufacturer-recommended substitute for the obsolete M80-8910401. Both connectors maintain identical mechanical and electrical compatibility across all critical mating parameters, including pitch, row configuration, contact geometry, and operating temperature range.

The M80-8500442 offers improved product lifecycle status as an active component with current manufacturing support and availability. The substitute provides enhanced voltage rating capability (800V versus 120V), which supports broader application requirements without compromising the original 120V specification.

The M80-8500442 achieves ROHS3 compliance, addressing regulatory requirements for new designs and production runs. The contact post finish change from tin-lead to tin aligns with lead-free manufacturing standards. The insulation material upgrade to polyamide (PA46) nylon 4/6 glass-filled provides improved thermal and mechanical properties compared to polyester glass-filled material.

The contact post length difference (0.118" versus 0.051") requires verification for PCB stack-up compatibility in existing designs, though mated stacking heights remain identical.

Frequently Asked Questions (FAQ)

Q: Are M80-8910401 and M80-8500442 mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.079"/2.00mm), row spacing (0.079"/2.00mm), number of positions (4), mounting type (through hole), and fastening mechanism (locking ramp). Mated stacking heights are identical at 7.23mm and 7.85mm.

Q: What is the primary reason for substitution?

A: The M80-8910401 is obsolete. The M80-8500442 is the active equivalent from Harwin Inc. with current manufacturing and supply chain support.

Q: Does the contact post length difference affect compatibility?

A: The M80-8500442 has a longer contact post (0.118" versus 0.051"). This difference must be evaluated against PCB through-hole depth and solder joint requirements in the specific application. Mated stacking heights remain unchanged.

Q: Is the M80-8500442 suitable for applications originally designed for 120V?

A: Yes. The M80-8500442 is rated for 800V, which exceeds the original 120V requirement. The substitute maintains full compatibility with 120V applications.

Q: What is the impact of the RoHS compliance change?

A: The M80-8500442 is ROHS3 compliant, while the M80-8910401 is non-compliant. For new production and designs subject to RoHS regulations, the M80-8500442 is required. For legacy systems, both parts remain functionally equivalent.

Q: Are there packaging differences?

A: The M80-8500442 is supplied in tube packaging. Original packaging for M80-8910401 is unspecified. Verify packaging requirements for your procurement and assembly processes.

Q: Do both connectors support the same temperature range?

A: Yes. Both parts operate across -55°C to 125°C with identical UL94 V-0 flammability rating.
