Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M20-8770546P is determined by strict equivalence across the following critical parameters:

• Connector type: Header, cuttable configuration
• Contact type: Male pin
• Number of positions: 5
• Pitch specification: 0.100" (2.54mm)
• Mounting type: Surface mount
• Termination method: Solder
• Operating temperature range: -40°C ~ 105°C
• Current rating: 3A per contact
• Contact material and finish: Brass with tin plating
• Insulation material: Polyamide (PA6T), Nylon 6T
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

The M20-8770546 qualifies as a direct substitute based on identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: M20-8770546 is active and available in production quantities, whereas M20-8770546P is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The M20-8770546 is the direct active equivalent for the obsolete M20-8770546P. Both parts maintain identical electrical and mechanical specifications, including contact configuration, pitch, current rating, operating temperature range, and material certifications. The M20-8770546 carries active product status with significantly higher inventory availability, making it the appropriate selection for new designs and ongoing production requirements.

Both parts satisfy ROHS3 compliance and UL94 V-0 flammability requirements. The packaging difference (tape and reel versus bulk) reflects standard distribution formats and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can M20-8770546 directly replace M20-8770546P in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 5-position, 2.54mm pitch, surface mount header with male pins, 3A per contact rating, and -40°C to 105°C operating range. The substitution is direct with no design modifications required.

Q: What is the significance of the "P" suffix in M20-8770546P?

A: The "P" designation indicates the part is packaged in tape and reel format. The M20-8770546 without the "P" suffix uses bulk packaging. Functional specifications remain identical.

Q: Are there any compliance or certification differences between these parts?

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

Q: Why is M20-8770546P listed as obsolete?

A: The M20-8770546P has been superseded by the M20-8770546 in the active product line. The active equivalent maintains all functional and electrical characteristics while offering improved availability and production support.

Q: What are the mated stacking height options for this connector?

A: The connector supports four mated stacking heights: 11.63mm, 12.23mm, 12.63mm, and 18.13mm. These options accommodate various application requirements for board-to-board spacing.

Q: Is this connector suitable for high-temperature applications?

A: The operating temperature range of -40°C to 105°C supports standard industrial and commercial applications. Applications requiring extended temperature ranges beyond 105°C require alternative connector designs.
