Key Parameters

Substitute Part Grouping Explanation

Substitution of the M80-8151222 is based on electrical and mechanical compatibility within the Datamate L-Tek series. The following parameters define acceptable substitutes:

• Identical pitch and row spacing (0.079" / 2.00mm)
• Matching position count (12 positions in 2 rows)
• Equivalent electrical ratings (2.2A current, 800V voltage)
• Compatible operating temperature range (-55°C ~ 125°C)
• Same mounting method (through-hole solder termination)
• Identical contact material and finish specifications
• Matching insulation material and flammability rating (UL94 V-0)

The M80-8541242 meets all these criteria as an active product within the same series, differing only in connector type designation (Header vs. Plug), fastening mechanism (Latch Holder vs. Friction Lock), insulation material composition (PPS vs. Polyester), and post contact finish (Tin vs. Tin-Lead).

Parameter Comparison

Engineering Selection Recommendations

The M80-8541242 is the designated manufacturer substitute for the obsolete M80-8151222. Both parts maintain identical electrical and mechanical specifications, ensuring functional compatibility in existing designs.

Key selection factors:

• The M80-8541242 is an active product with current manufacturing support, whereas the M80-8151222 is obsolete
• The M80-8541242 achieves ROHS3 compliance, addressing regulatory requirements for new designs
• The M80-8541242 features improved insulation material (Polyphenylene Sulfide) compared to the polyester composition of the original part
• Both parts are available in production quantities and share identical mating characteristics, pitch, and electrical ratings

For applications requiring the original M80-8151222, the M80-8541242 provides direct functional replacement with enhanced compliance and material specifications.

Frequently Asked Questions (FAQ)

Q: Can the M80-8541242 directly replace the M80-8151222 in existing designs?

A: Yes. Both parts share identical electrical ratings (2.2A, 800V), mechanical dimensions, pitch (2.00mm), position count (12 in 2 rows), and contact specifications. The M80-8541242 is the manufacturer-designated substitute.

Q: What are the differences between these two parts?

A: The primary differences are product status (M80-8151222 is obsolete; M80-8541242 is active), RoHS compliance (M80-8541242 is ROHS3 compliant), insulation material (M80-8541242 uses PPS vs. polyester), fastening mechanism (Latch Holder vs. Friction Lock), and post contact finish (Tin vs. Tin-Lead).

Q: Are the mating characteristics identical?

A: Yes. Both parts have identical mating pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), contact finish (gold), and mated stacking heights (7.23mm, 7.85mm, 10.2mm, 14.61mm).

Q: What is the packaging difference?

A: The M80-8151222 packaging is not specified in available data. The M80-8541242 is supplied in tube packaging.

Q: Does the change in insulation material affect performance?

A: Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range (-55°C ~ 125°C). The PPS material in the M80-8541242 provides enhanced chemical resistance and dimensional stability.

Q: Is the M80-8541242 suitable for new designs?

A: Yes. The M80-8541242 is an active product with ROHS3 compliance, making it the appropriate choice for new designs requiring this connector type and specifications.
