Substitute Part Grouping Explanation

The M20-8770442R qualifies as a direct substitute for the M20-8770442P based on identical electrical and mechanical parameters. Both parts share the same base product number (M20-877), connector configuration, contact specifications, and performance ratings. The substitution is valid across all critical parameters: 4-position layout, 2.54mm pitch, surface mount configuration, 3A per contact current rating, -40°C to 105°C operating temperature range, gold mating contact finish, and UL94 V-0 flammability rating.

The primary distinction between these parts is packaging format and product status. The M20-8770442P is supplied in standard packaging and carries obsolete status, while the M20-8770442R is supplied in Tape & Reel (TR) format and maintains active product status. This packaging difference does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The M20-8770442R is the appropriate selection for applications currently specified with M20-8770442P. Both parts maintain identical compliance certifications including ROHS3 compliance, REACH unaffected status, and UL94 V-0 flammability rating. The M20-8770442R's active product status ensures continued availability and supply chain stability compared to the obsolete M20-8770442P.

For new designs or production transitions, M20-8770442R is the recommended part number. The Tape & Reel packaging format of the M20-8770442R provides advantages for automated assembly processes and high-volume manufacturing operations. No design modifications or PCB layout changes are required when transitioning from M20-8770442P to M20-8770442R.

Frequently Asked Questions (FAQ)

Q: Can M20-8770442R directly replace M20-8770442P in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including connector configuration, contact ratings, operating temperature range, and material specifications. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. M20-8770442P is obsolete and supplied in standard packaging, while M20-8770442R is active and supplied in Tape & Reel format. All electrical and mechanical specifications are identical.

Q: Is the Tape & Reel packaging compatible with existing assembly processes?

A: Tape & Reel packaging is standard for automated surface mount assembly. If your current process uses standard packaging, coordination with your assembly partner may be necessary to accommodate the TR format, though the component itself is identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical compliance certifications: ROHS3 compliant, REACH unaffected, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity level.

Q: Why is M20-8770442P listed as obsolete?

A: Manufacturer product status classifications reflect production and support decisions. The M20-8770442R maintains the same design and specifications while offering active product status and continued manufacturer support.
