Key Parameters

Substitute Part Grouping Explanation

The 6STD09SAM99B70X qualifies as a direct substitute for the 6STD09SAM99B50X based on the following matching parameters:

Electrical Compatibility:

• Identical connector style (D-Sub) and type (Receptacle, Female Sockets)
• Matching position count (9 positions, 2 rows)
• Identical shell size and connector layout (1 DE, E)
• Equivalent current rating (7.5A) and voltage rating (125V)
• Matching operating temperature range (-25°C ~ 105°C)

Mechanical Compatibility:

• Identical mounting type (Panel Mount)
• Matching termination method (Solder Cup)
• Equivalent shell material and finish (Copper Alloy, Tin Plated)
• Matching contact finish (Gold)
• Identical contact form (Machined)

Regulatory Compliance:

• Both parts are ROHS3 compliant
• Both parts are REACH unaffected
• Both parts carry UL94 V-0 flammability rating
• Both parts have MSL rating of 1 (Unlimited)

Key Differentiators: The substitute part 6STD09SAM99B70X is currently active in production, whereas the main part is obsolete. The substitute features mating side flange only (versus cable side and mating side flanges on the main part) and includes mounting hardware. Contact finish thickness differs (Flash versus 8.00µin on the main part).

Parameter Comparison

Engineering Selection Recommendations

The 6STD09SAM99B70X is the appropriate substitute for the obsolete 6STD09SAM99B50X. Both connectors meet identical electrical and mechanical specifications for 9-position D-Sub receptacle applications. The substitute part is currently in active production status, ensuring availability for new designs and replacement procurement.

Both parts satisfy ROHS3 compliance requirements and REACH regulatory status. The UL94 V-0 flammability rating is maintained across both parts, supporting applications requiring flame-resistant materials. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part.

The primary advantage of selecting the 6STD09SAM99B70X is its active product status and inclusion of mounting hardware. The electrical performance, mechanical interface, and environmental protection ratings remain equivalent to the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the 6STD09SAM99B70X directly replace the 6STD09SAM99B50X in existing applications?

A: Yes. Both connectors share identical electrical ratings (7.5A, 125V), mechanical configuration (9-position, panel mount, solder cup termination), and environmental protection (IP67). The operating temperature range and contact specifications are equivalent.

Q: What is the difference in flange configuration between these parts?

A: The 6STD09SAM99B50X features flanges on both the cable side and mating side (4-40). The 6STD09SAM99B70X features a flange on the mating side only (4-40). This difference does not affect electrical compatibility but may impact mechanical mounting considerations in specific panel configurations.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings. Moisture sensitivity levels are identical (MSL 1, Unlimited).

Q: What is the significance of the contact finish thickness difference?

A: The 6STD09SAM99B50X specifies 8.00µin (0.203µm) gold contact finish thickness, while the 6STD09SAM99B70X specifies flash gold finish. Both finishes provide equivalent corrosion resistance and electrical performance for signal-level applications at the specified current and voltage ratings.

Q: Does the substitute part include additional features?

A: The 6STD09SAM99B70X includes mounting hardware as a standard feature, whereas this is not specified for the main part. This addition supports simplified installation in panel mount applications.

Q: What is the inventory status for these parts?

A: The 6STD09SAM99B50X has 801 pieces in stock (obsolete status). The 6STD09SAM99B70X has 829 pieces in stock (active status). For new procurement, the active part should be specified.
