Key Parameters

Substitute Part Grouping Explanation

The M80-8540442 qualifies as a direct substitute for the M80-8630422 based on the following critical parameters:

Matching Electrical Specifications:

• Identical pitch: 0.079" (2.00mm)
• Identical row spacing: 0.079" (2.00mm)
• Identical position count: 4 positions in 2 rows
• Identical current rating: 2.2A
• Identical voltage rating: 800V
• Identical operating temperature range: -55°C ~ 125°C

Matching Mechanical Specifications:

• Same connector type: Header
• Same contact type: Male Pin
• Same mounting type: Through Hole
• Same termination: Solder
• Same shrouding: Shrouded - 4 Wall
• Same insulation height: 0.219" (5.56mm)
• Same contact post length: 0.118" (3.00mm)
• Same mated stacking heights: 7.23mm, 7.85mm, 10.2mm, 14.61mm

Matching Material & Contact Specifications:

• Same contact material: Phosphor Bronze
• Same contact finish on mating surface: Gold at 29.5µin (0.75µm)
• Same contact finish thickness on post: 118.1µin (3.00µm)
• Same material flammability rating: UL94 V-0
• Same insulation color: Black

The primary differences are product status (Active vs. Obsolete), fastening type (Latch Holder vs. Friction Lock), insulation material composition, contact finish post material (Tin vs. Tin-Lead), and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The M80-8540442 is the appropriate substitute for the obsolete M80-8630422. Both components maintain identical electrical and mechanical specifications across all critical parameters including pitch, position count, current and voltage ratings, and operating temperature range.

The M80-8540442 offers the advantage of active product status, ensuring ongoing availability and manufacturing support. Additionally, the substitute achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This compliance status is significant for applications subject to regulatory requirements.

The change in insulation material from Polyamide (PA46) Nylon 4/6 to Polyphenylene Sulfide (PPS) Glass Filled, combined with the shift from Tin-Lead to Tin contact finish on the post, reflects modern manufacturing standards while maintaining equivalent electrical performance and thermal characteristics.

The fastening mechanism differs between the two parts (Friction Lock versus Latch Holder), which may affect mating force characteristics and connector retention behavior. This distinction should be evaluated within the context of the specific application's mechanical requirements.

Frequently Asked Questions (FAQ)

Q: Are the M80-8630422 and M80-8540442 electrically interchangeable?

A: Yes. Both components share identical electrical specifications: 2.2A current rating, 800V voltage rating, and -55°C to 125°C operating temperature range. The gold-plated mating contacts and phosphor bronze contact material are identical in both parts.

Q: What is the significance of the fastening type difference (Friction Lock vs. Latch Holder)?

A: The fastening type affects how the connector maintains mating force and retention. Friction Lock relies on contact pressure alone, while Latch Holder incorporates a mechanical locking mechanism. The choice depends on application requirements for connector retention and mating force stability.

Q: Does the insulation material change affect performance?

A: The insulation material change from Polyamide (PA46) Nylon 4/6 to Polyphenylene Sulfide (PPS) Glass Filled does not affect the electrical or thermal performance within the specified operating range. Both materials achieve UL94 V-0 flammability rating. PPS offers enhanced chemical resistance and dimensional stability.

Q: Why is RoHS compliance important for this substitution?

A: The M80-8540442 achieves ROHS3 compliance, whereas the M80-8630422 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part provides regulatory alignment. The Tin post finish on the substitute part supports RoHS compliance objectives.

Q: Are the pitch and row spacing identical?

A: Yes. Both parts maintain 0.079" (2.00mm) pitch for mating and identical 0.079" (2.00mm) row spacing. This ensures mechanical compatibility with existing mating connectors and PCB layouts.

Q: What is the packaging difference?

A: The M80-8630422 packaging is not specified in the available data. The M80-8540442 is supplied in Tube packaging. Packaging format may affect handling, storage, and integration into assembly processes.

Q: Are the contact post lengths identical?

A: Yes. Both parts feature 0.118" (3.00mm) contact post length, ensuring compatibility with standard PCB through-hole depths and solder joint formation.
