Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 171-037-112-021 are grouped based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• Connector Type: D-Sub Plug with Male Pins
• Number of Positions: 37
• Number of Rows: 2
• Shell Size / Connector Layout: 4 (DC, C)
• Termination Method: Solder
• Contact Type: Signal
• Material Flammability Rating: UL94 V-0
• RoHS Compliance Status: ROHS3 Compliant or RoHS Compliant

Secondary Compatibility Factors:

• Mounting Type: Panel Mount or Through Hole configurations
• Shell Material: Steel construction
• Contact Finish: Gold or unspecified finishes
• Operating Temperature Range: -50°C to 100°C or -55°C to 125°C

Parts meeting all primary criteria are classified as direct substitutes. Parts meeting primary criteria with variations in mounting configuration or contact finish are classified as compatible alternatives.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

171-037-113R021 (NorComp Inc.) is the primary direct substitute for 171-037-112-021. Both parts share identical specifications across all critical parameters including connector type, position count, shell size, mounting configuration, and termination method. Both maintain ROHS3 compliance and UL94 V-0 flammability rating. This part is recommended as the first alternative when 171-037-112-021 is unavailable.

SDCB-37P(55) (Hirose Electric Co Ltd) is a compatible substitute meeting all primary matching criteria. The part maintains identical connector specifications and panel mount configuration. RoHS compliance status differs (RoHS Compliant versus ROHS3 Compliant), but both certifications satisfy regulatory requirements. This part is suitable for applications where cross-manufacturer sourcing is acceptable.

Compatible Alternatives (Mounting Configuration Variation):

HARTING parts 09654296702, 09654296701, 09654616711, 09654616712, 09664216701, 09664216703, and 09664217703 are compatible alternatives that meet all primary electrical and mechanical specifications. These parts differ in mounting type (Through Hole only, without panel mount designation) and flange feature configurations. All maintain ROHS3 compliance and UL94 V-0 flammability rating. Selection of these alternatives requires confirmation that the application accommodates through-hole mounting without panel mount requirements.

All substitute parts listed are active products with confirmed inventory availability and comply with applicable regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can 171-037-113R021 be used as a direct replacement for 171-037-112-021?

A: Yes. Both parts are NorComp Inc. products with identical specifications across connector type, position count, shell size, mounting configuration, and termination method. Both are ROHS3 compliant and rated UL94 V-0. The parts are functionally interchangeable.

Q: What is the difference between the NorComp and HARTING substitute options?

A: NorComp parts (171-037-112-021 and 171-037-113R021) and Hirose part SDCB-37P(55) feature panel mount configuration with through-hole termination. HARTING parts feature through-hole mounting only without panel mount designation. All parts maintain identical 37-position, 2-row D-Sub plug configuration with solder termination and UL94 V-0 rating.

Q: Are all listed substitutes ROHS compliant?

A: Yes. All substitute parts listed are either ROHS3 compliant or RoHS compliant. Both certifications satisfy current regulatory requirements for electronic components.

Q: What mounting configurations are available among the substitute parts?

A: The NorComp 171-037-113R021 and Hirose SDCB-37P(55) support panel mount with through-hole configuration.
