Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 172-E15-212-021 is determined by the following critical parameters:

• Connector Configuration: 15-position receptacle with 2-row layout, shell size 2 (DA, A)
• Connector Type: Female sockets for signal contact
• Electrical Performance: 5A current rating capability
• Termination Compatibility: Solder or press-fit termination methods
• Environmental Compliance: RoHS3 compliance and operating temperature range

The substitute parts identified maintain these core electrical and mechanical specifications while varying in mounting approach, shell finish, contact material composition, and termination method. All substitutes are active products with current manufacturing status and maintain the 15-position, 2-row D-Sub receptacle configuration.

Parameter Comparison

Engineering Selection Recommendations

172-E15-213R021 (NorComp Inc.) represents the closest direct equivalent, maintaining identical electrical specifications, operating temperature range, and mounting configuration. Both parts share the same base product number (172-E) and series designation. This substitute is suitable for applications where NorComp sourcing is preferred and inventory availability is a consideration (1223 units in stock).

1757834-2 (TE Connectivity Aerospace, Defense and Marine) qualifies as a substitute for applications requiring extended operating temperature range (-55°C ~ 125°C) and military-grade specifications under MIL-DTL-24308. This part is appropriate for aerospace, defense, and marine environments where enhanced temperature performance and military compliance are mandatory. The yellow chromate plated zinc finish provides corrosion resistance suitable for harsh environments.

5786144-1 (TE Connectivity AMP Connectors) offers press-fit termination as an alternative to solder attachment, suitable for automated assembly processes and applications requiring rapid board-level integration. The AMPLIMITE HD-20 series designation indicates high-density connector design. This substitute is applicable when press-fit termination methodology aligns with manufacturing processes and the extended operating temperature range (-55°C ~ 105°C) meets application requirements.

All substitute parts maintain RoHS3 compliance and the core 15-position, 2-row D-Sub receptacle configuration with shell size 2 (DA, A) layout.

Frequently Asked Questions (FAQ)

Q: Can 172-E15-213R021 be used as a direct replacement for 172-E15-212-021?

A: Yes. Both parts are manufactured by NorComp Inc., share the same series designation (172-E), maintain identical electrical specifications (5A current rating), operating temperature range (-50°C ~ 100°C), and panel mount through-hole configuration with solder termination. The primary difference is packaging format (tray vs. standard).

Q: What is the key difference between solder and press-fit termination options?

A: Solder termination (172-E15-212-021, 172-E15-213R021, 1757834-2) requires wave or reflow soldering processes for board attachment. Press-fit termination (5786144-1) uses mechanical insertion into plated through-holes without solder, enabling faster assembly and reduced thermal stress on components. Selection depends on manufacturing process capability and application requirements.

Q: Is 1757834-2 suitable for non-military applications?

A: Yes. While 1757834-2 meets military specifications (MIL-DTL-24308), it functions as a standard D-Sub receptacle in any application. The extended operating temperature range (-55°C ~ 125°C) and enhanced environmental specifications provide additional margin for demanding industrial or commercial applications. Military compliance does not restrict civilian use.

Q: What mounting differences exist between these substitutes?

A: 172-E15-212-021 and 172-E15-213R021 feature panel mount configuration with board-side flange (4-40). 1757834-2 and 5786144-1 use through-hole mounting without panel mount flange, requiring different PCB layout and mechanical support structures. Verify mounting compatibility with your application before substitution.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All four parts (172-E15-212-021, 172-E15-213R021, 1757834-2, and 5786144-1) maintain ROHS3 compliance, meeting current environmental and hazardous substance restrictions for electronic components.

Q: Which substitute offers the widest operating temperature range?

A: 1757834-2 provides the widest operating temperature specification at -55°C ~ 125°C, compared to -50°C ~ 100°C for the main part and 172-E15-213R021, and -55°C ~ 105°C for 5786144-1. This extended range is beneficial for applications in extreme thermal environments.
