BB-232SGM D-Sub Gender Changer DB25M to DB25M Equivalent & Substitute Parts
Part Overview
The BB-232SGM is a D-Sub gender changer adapter manufactured by Advantech Corp, designed to connect two D-Sub 25-pin male connectors in a free-hanging (in-line) configuration. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring this connector type.

Substitute Part Grouping Explanation
Substitution eligibility for the BB-232SGM is determined by the following critical parameters:
- Connector Configuration: Both ends must be D-Sub 25-pin male connectors
- Adapter Function: Must operate as a gender changer in free-hanging (in-line) orientation
- Pin Count and Row Configuration: 25 pins arranged in 2 rows
- Electrical Ratings: Voltage rating of 300 V and current rating capability
- Contact Material: Gold-plated contacts for signal integrity
- Mechanical Features: Grounding indents for proper shielding alignment
The AB414 from Assmann WSW Components meets all these substitution criteria, maintaining functional and electrical equivalence with the obsolete BB-232SGM.

| Convert To (Adapter End) | D-Sub, 25 Pin Male | D-Sub, 25 Pin Male | Match |
| Number of Rows | 2 | 2 | Match |
| Mounting Type | Free Hanging (In-Line) | Free Hanging (In-Line) | Match |
| Features | Grounding Indents | Grounding Indents | Match |
| Voltage Rating | 300 V | 300 V | Match |
| Current Rating | 5 A | 3 A | Partial - AB414 rated lower |
| Contact Finish | Gold | Gold | Match |
| Product Status | Obsolete | Active | AB414 actively manufactured |
Engineering Selection Recommendations
The AB414 is the direct functional equivalent for the obsolete BB-232SGM. Both components provide identical D-Sub 25-pin male-to-male gender changer functionality with matching mechanical and electrical specifications.
The AB414 offers additional advantages for new designs and replacements:
- Active Product Status: Currently manufactured and supported by Assmann WSW Components
- RoHS3 Compliance: Meets current environmental and regulatory requirements
- REACH Unaffected: Compliant with chemical substance regulations
- Material Certification: UL94 V-0 flammability rating provides enhanced safety documentation
- Packaging: Supplied with jack screws and protective bag packaging
The current rating difference (AB414 rated at 3 A versus BB-232SGM at 5 A) must be evaluated against application requirements. Applications requiring current levels above 3 A should be assessed for alternative solutions or current derating considerations.
Frequently Asked Questions (FAQ)
Q: Can the AB414 directly replace the BB-232SGM in existing installations?
A: Yes, the AB414 provides direct mechanical and electrical substitution. Both components feature identical D-Sub 25-pin male connectors, free-hanging mounting, and gold-plated contacts. Verify that your application current requirements do not exceed the AB414 rating of 3 A.
Q: What is the significance of the current rating difference between these parts?
A: The BB-232SGM is rated for 5 A while the AB414 is rated for 3 A. This difference reflects manufacturing specifications and design margins. Applications operating at currents between 3 A and 5 A require evaluation of actual system demands and thermal considerations.
Q: Why is the BB-232SGM listed as obsolete?
A: Obsolete status indicates the part is no longer manufactured by Advantech Corp. The AB414 provides continued availability of equivalent functionality from an active manufacturer.
Q: Are there packaging differences between these components?
A: The BB-232SGM packaging information is not specified. The AB414 is supplied in bag packaging and includes 3 pieces: 1 connector and 2 jack screws. Verify packaging requirements for your procurement and assembly processes.
Q: What compliance certifications apply to the AB414?
A: The AB414 carries RoHS3 compliance, REACH unaffected status, and UL94 V-0 flammability certification. These certifications support use in regulated applications and environments with specific material requirements.
Q: Are the grounding indents functionally equivalent on both parts?
A: Yes, both the BB-232SGM and AB414 feature grounding indents. This design element ensures proper shielding alignment and signal integrity in D-Sub connector applications.
