Key Parameters

Substitute Part Grouping Explanation

Substitution of the M80-4555098 is based on strict equivalence of the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 50 positions at 0.079" (2.00mm) pitch
• Row Configuration: 2 rows with 0.079" (2.00mm) row spacing
• Mounting & Termination: Free hanging (in-line) with crimp termination
• Mechanical Features: Jackscrews for secure mating
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The M80-4615005 from Harwin Inc.'s Datamate J-Tek series satisfies all substitution criteria. Both connectors maintain identical electrical and mechanical interfaces, enabling direct replacement in applications requiring 50-position, 2.00mm pitch receptacle housings with crimp termination.

Parameter Comparison

Engineering Selection Recommendations

The M80-4615005 is the direct equivalent for the obsolete M80-4555098. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The M80-4615005 offers the advantage of active product status with current manufacturing support and documented availability. Both connectors carry ROHS3 compliance and MSL 1 ratings, ensuring compatibility with modern supply chain and environmental requirements. Selection of the M80-4615005 eliminates obsolescence risk while preserving full interface compatibility with existing mating components and cable assemblies.

Frequently Asked Questions (FAQ)

Q: Can the M80-4615005 directly replace the M80-4555098 in existing applications?

A: Yes. Both connectors share identical pitch (2.00mm), position count (50), row configuration (2 rows), mounting type (free hanging in-line), and termination method (crimp). Mating interfaces and mechanical envelopes are equivalent.

Q: What is the primary reason for substitution?

A: The M80-4555098 is classified as obsolete. The M80-4615005 is an active product from the same manufacturer with identical specifications, providing continued availability and manufacturing support.

Q: Are there differences in contact specifications between these parts?

A: The M80-4615005 specifies wire gauge compatibility (24-28 AWG) and contact finish (gold, 11.8µin thickness). The M80-4555098 documentation does not include these contact details. Both housings accept crimp termination and are compatible with standard Datamate series contacts.

Q: Do both connectors meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity level), and are REACH unaffected. Operating temperature range is -55°C to 125°C for both.

Q: What is the difference between the Datamate Trio-Tek and Datamate J-Tek series?

A: Both are Harwin rectangular connector series with 2.00mm pitch. The J-Tek series (M80-4615005) represents the current active product line, while Trio-Tek (M80-4555098) is obsolete. Electrical and mechanical interfaces remain compatible.
