Key Parameters

Substitute Part Grouping Explanation

Substitution of the M20-9711245 is determined by the following critical parameters that must remain constant:

• Connector Type & Series: Header, Cuttable design within the M20 series
• Contact Configuration: Male pin, 12-position, single-row layout
• Pitch Specification: 0.100" (2.54mm) mating pitch
• Mounting Method: Through-hole, right-angle orientation
• Electrical Performance: 3A per contact current rating
• Termination: Solder attachment
• Environmental Compliance: UL94 V-0 flammability, ROHS3 compliance, operating range -40°C to 105°C

The M20-9961245 qualifies as a direct substitute based on these parameters. Both parts share identical connector type, pitch, position count, mounting configuration, current rating, and environmental specifications. The primary difference is product status: M20-9961245 is active production, whereas M20-9711245 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The M20-9961245 is the direct active equivalent for the obsolete M20-9711245. Selection of M20-9961245 is supported by:

• Product Status: M20-9961245 maintains active production status, ensuring long-term availability and supply chain continuity
• Compliance Alignment: Both parts maintain identical ROHS3 compliance and REACH unaffected status
• Electrical & Mechanical Equivalence: All critical parameters including pitch, position count, current rating, and operating temperature range are identical
• Contact Geometry Variation: The mating contact length differs by 0.036" (0.90mm), representing a minor dimensional variation that does not affect functional compatibility within standard PCB mounting applications
• Certification Maintenance: UL94 V-0 flammability rating and MSL 1 classification are preserved

For new designs or component refresh cycles, M20-9961245 should be specified to ensure procurement reliability and compliance with current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can M20-9961245 be used as a direct replacement for M20-9711245 in existing assemblies?

A: Yes. Both connectors share identical pitch (0.100"), position count (12), mounting type (through-hole right-angle), contact type (male pin), and current rating (3A per contact). The mating contact length difference of 0.036" does not affect standard PCB mounting compatibility.

Q: What is the significance of the contact length variation between these parts?

A: The M20-9711245 features a 0.276" (7.00mm) mating contact length, while M20-9961245 has 0.240" (6.10mm). This 0.036" difference is a minor dimensional variation that remains within acceptable tolerance for board-to-board and cable connection applications. Both maintain identical post length (0.118") and insulation height (0.100").

Q: Are there packaging differences between M20-9711245 and M20-9961245?

A: M20-9711245 is supplied without specified packaging designation, while M20-9961245 is supplied in bulk packaging. This distinction affects procurement and handling but does not impact electrical or mechanical performance.

Q: Why is M20-9711245 classified as obsolete?

A: M20-9711245 has been discontinued from active production. M20-9961245 represents the current active production equivalent within the M20 series, ensuring ongoing availability and compliance with current manufacturing standards.

Q: Do both connectors maintain the same environmental and compliance certifications?

A: Yes. Both M20-9711245 and M20-9961245 are ROHS3 compliant, REACH unaffected, UL94 V-0 rated, and operate across the identical temperature range of -40°C to 105°C with MSL 1 classification.

Q: Is there any difference in contact material or finish between these parts?

A: No. Both connectors feature brass contacts with gold plating on the mating surface, identical insulation material (Polyamide PA6T/Nylon 6T), and black insulation color.
