HARTING 09644127245 D-Sub 37-Position Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The HARTING 09644127245 is a 37-position D-Sub receptacle connector with female sockets, designed for through-hole solder termination applications. This connector features a board-side flange with 4-40 mounting, steel shell construction, and operates across a temperature range of -20°C to 125°C. The part is currently active in production with 1,056 units in stock.

Equivalent and substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits the use of alternative manufacturers' components that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09644127245 is determined by strict alignment of the following core parameters:

Critical Parameters (Must Match Exactly):

• Connector type: D-Sub receptacle, female sockets
• Number of positions: 37
• Number of rows: 2
• Shell size and layout: 4 (DC, C)
• Mounting type: Through hole
• Termination method: Solder
• Material flammability rating: UL94 V-0

Allowable Variations:

• Manufacturer identity (HARTING to TE Connectivity AMP Connectors)
• Shell material finish (steel to steel with tin plating)
• Contact finish (unspecified to gold flash)
• Contact material (copper alloy to phosphor bronze)
• Dielectric material (PCT to thermoplastic or polyamide)
• Flange feature (board side to housing/shell unthreaded, or board side variations)
• Operating temperature range (may extend beyond original specification)
• Voltage rating (may exceed original specification)
• Current rating (may differ within acceptable limits)
• Packaging format (bulk to tube)

The five substitute parts listed below meet these criteria and are classified as direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

TE Connectivity 5745189-7 and 5745189-1 are the preferred substitutes. Both parts carry ROHS3 compliance (5745189-7) or ROHS3 compliance (5745189-1), matching the regulatory status of the original HARTING component. These parts are from the AMPLIMITE HDP-20 series and feature extended operating temperature range (-55°C to 105°C) and higher voltage rating (125V) compared to the original specification. Inventory availability is strong at 1,761 units (5745189-7) and 1,164 units (5745189-1).

Secondary Substitutes (Conditional Use):

TE Connectivity 5747315-1 and 747315-1 are functionally equivalent alternatives from the AMPLIMITE HD-20 series. The 5747315-1 maintains RoHS compliance and board-side flange mounting identical to the original part. The 747315-1 offers the same mechanical and electrical characteristics but carries "Not applicable" RoHS status and "REACH Affected" designation, making it suitable only for applications where RoHS compliance is not required.

Not Recommended:

TE Connectivity 745189-7 is classified as RoHS non-compliant and should not be selected for new designs or applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity parts directly replace the HARTING 09644127245 without PCB redesign?

A: Substitution feasibility depends on flange feature compatibility. Parts with board-side flange mounting (5747315-1, 747315-1) are mechanically interchangeable with the original HARTING component. Parts with housing/shell unthreaded flange (5745189-1, 5745189-7, 745189-7) require PCB layout modification to accommodate the different mounting interface.

Q: What is the impact of the lower current rating (6A vs. 7.5A) in the substitute parts?

A: The substitute parts are rated for 6A continuous current, compared to 7.5A for the original HARTING part. Applications operating at or below 6A current per contact are unaffected. Applications requiring the full 7.5A rating must retain the original HARTING component.

Q: Are the substitute parts compatible with existing connector mates?

A: Yes. All substitute parts maintain the same D-Sub 37-position, 2-row configuration with shell size 4 (DC, C) layout. Mating with standard D-Sub 37-position plugs is fully compatible.

Q: What is the difference between ROHS3 Compliant, RoHS Compliant, and RoHS non-compliant designations?

A: ROHS3 Compliant indicates compliance with the most recent RoHS 3 directive (2011/65/EU as amended). RoHS Compliant indicates compliance with earlier RoHS directives. RoHS non-compliant parts do not meet any RoHS standard and are restricted in markets requiring RoHS certification.

Q: Does the extended operating temperature range of the substitute parts (-55°C to 105°C) affect compatibility?

A: The substitute parts support a wider low-temperature range (-55°C vs. -20°C) but a narrower high-temperature range (105°C vs. 125°C). Applications operating between 105°C and 125°C require the original HARTING part. Applications within -55°C to 105°C are fully compatible.

Q: What packaging considerations apply when ordering substitute parts?

A: The original HARTING part is supplied in bulk packaging. All TE Connectivity substitutes are supplied in tube packaging. Tube packaging provides improved protection during storage and handling but may require different receiving and inventory procedures.

Q: Which substitute part offers the best overall compatibility?

A: TE Connectivity 5745189-7 provides the strongest compatibility profile: ROHS3 compliance matching the original part, highest inventory availability (1,761 units), and extended electrical specifications (125V, -55°C to 105°C). The housing/shell unthreaded flange requires PCB modification but is functionally equivalent.
