Key Parameters

Substitute Part Grouping Explanation

The substitute part 982-037-020R121 is functionally equivalent to the main part based on the following critical parameters that determine substitution validity:

• Number of Positions: Both parts maintain 37-position configuration
• Compatible Shell Size: Both support Shell Size C
• Compatible D-Sub Size: Both support 37pos and HD62pos connectors
• Cable Exit Angles: Both provide 90° and 180° exit options
• Shielding Configuration: Both are shielded constructions
• Accessory Type: Both are two-piece backshell designs
• Cable Type: Both accommodate round cables
• Material Composition: Both use plastic with metallized construction
• Plating Specification: Both feature nickel over copper plating
• Hardware Configuration: Both include assembly hardware and strain relief with 4-40 mating screws
• Color: Both are silver

The primary distinction between these parts is product status and compliance certification, not functional or mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The 982-037-020R121 is the direct active-status equivalent for the obsolete 982-037-020-121. Selection between these parts should be based on the following criteria:

For New Designs and Forward-Compatible Applications: The 982-037-020R121 is the appropriate choice. This part carries active product status, ROHS3 compliance certification, and defined moisture sensitivity level (MSL 1 - Unlimited), meeting current regulatory and environmental standards.

For Legacy System Maintenance: The 982-037-020-121 remains functionally compatible with existing assemblies due to identical mechanical and electrical parameters. However, the obsolete status indicates limited future availability.

Compliance Considerations: The 982-037-020R121 provides ROHS3 compliance, whereas the main part is RoHS non-compliant. Applications subject to RoHS regulations require the substitute part.

Both parts share identical functional specifications across all critical parameters: position count, shell size compatibility, cable exit angles, shielding, material composition, and hardware configuration.

Frequently Asked Questions (FAQ)

Q: Are these parts mechanically interchangeable?

A: Yes. Both the 982-037-020-121 and 982-037-020R121 share identical mechanical specifications including shell size C compatibility, 37-position configuration, two-piece backshell design, and cable exit angle options (90° and 180°).

Q: What is the primary difference between these parts?

A: The primary differences are product status (obsolete versus active), RoHS compliance certification (non-compliant versus ROHS3 compliant), and packaging format. All functional and mechanical parameters are identical.

Q: Can the 982-037-020R121 replace the 982-037-020-121 in existing assemblies?

A: Yes. The substitute part maintains full compatibility with applications designed for the original part due to matching dimensional, electrical, and mechanical specifications.

Q: Which part should be specified for new designs?

A: The 982-037-020R121 should be specified for new designs. This part has active product status and current regulatory compliance certifications.

Q: Are there packaging differences between these parts?

A: Yes. The 982-037-020R121 is supplied in bag packaging, while packaging information for the 982-037-020-121 is not specified in the technical data.

Q: What does MSL 1 (Unlimited) mean for the substitute part?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions without requiring special moisture control measures.

Q: Are both parts RoHS compliant?

A: No. The 982-037-020-121 is RoHS non-compliant, while the 982-037-020R121 is ROHS3 compliant. Applications requiring RoHS compliance must use the substitute part.
