Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DDMM50SH is determined by the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Connector type: Receptacle, Female Sockets
• Number of positions: 50
• Number of rows: 3
• Shell size and layout: 5 (DD, D)
• Termination method: Solder
• Contact type: Signal

Performance Parameters (Must Meet or Exceed):

• Current rating: Minimum 7.5A
• Operating temperature range: Must encompass -55°C to 150°C
• Material flammability rating: UL94 V-0 or equivalent

Compliance Parameters:

• RoHS compliance status: RoHS Compliant or ROHS3 Compliant

The HARTING part number 09665116502 qualifies as a substitute based on matching connector configuration, position count, row arrangement, shell size, solder termination, and signal contact type. Both parts maintain D-Sub receptacle architecture with identical electrical and mechanical interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both the DDMM50SH and 09665116502 are active production parts with current RoHS compliance certifications. The DDMM50SH maintains a higher current rating of 7.5A and extended operating temperature range to 150°C. The HARTING 09665116502 operates within a narrower temperature envelope (maximum 125°C) and carries a reduced current rating of 6.5A.

Selection between these parts should be based on application requirements. If the design operates at temperatures above 125°C or requires sustained current loads exceeding 6.5A, the DDMM50SH is the appropriate choice. For applications within the HARTING part's thermal and current specifications, the 09665116502 provides equivalent D-Sub receptacle functionality with identical connector geometry and pin configuration.

Both parts carry UL94 V-0 flammability ratings and maintain RoHS compliance, satisfying standard regulatory requirements for industrial and commercial connector applications.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09665116502 be used as a direct replacement for the DDMM50SH in all applications?

A: The HARTING part provides mechanical and electrical interface compatibility for D-Sub 50 position receptacle applications. However, application-specific thermal and current requirements must be evaluated. The HARTING part's maximum operating temperature of 125°C and current rating of 6.5A are lower than the DDMM50SH specifications. Substitution is valid only when application demands remain within these limits.

Q: What are the key differences between these two 50 position D-Sub receptacles?

A: Both connectors share identical mechanical interfaces: 50 positions, 3-row configuration, shell size 5 (DD, D), solder termination, and UL94 V-0 flammability rating. Differences include current rating (DDMM50SH 7.5A vs. HARTING 6.5A), maximum operating temperature (DDMM50SH 150°C vs. HARTING 125°C), shell finish (DDMM50SH yellow chromate plated zinc vs. HARTING steel), and contact finish specification (DDMM50SH gold vs. HARTING unspecified).

Q: Are there packaging differences between these parts?

A: The DDMM50SH packaging is not specified in available documentation. The HARTING 09665116502 is supplied in tray packaging. Packaging format should be confirmed with suppliers based on procurement and assembly requirements.

Q: Do both parts meet current RoHS requirements?

A: Yes. The DDMM50SH is RoHS Compliant, and the HARTING 09665116502 is ROHS3 Compliant. Both parts satisfy current RoHS directive requirements for electronic component procurement.

Q: What is the contact form difference between these connectors?

A: The DDMM50SH uses machined contacts, while the HARTING 09665116502 uses stamped contacts. Both contact forms are standard in D-Sub connector manufacturing and provide equivalent signal integrity for 50 position receptacle applications.
