Key Parameters

Substitute Part Grouping Explanation

Substitution between 1-103735-9 and 6-103735-9 is based on identical electrical and mechanical parameters. Both parts share the same connector type (Header), contact type (Male Pin), number of positions (20), mating pitch (0.100"), mounting method (Through Hole), shrouding configuration (Shrouded - 4 Wall), current rating (3A), operating temperature range (-65°C ~ 105°C), contact finish on mating surfaces (Gold at 30.0µin thickness), and material flammability rating (UL94 V-0).

The primary differences between these parts are:

Contact Finish - Post: 1-103735-9 uses Tin-Lead plating, while 6-103735-9 uses Tin plating. Both maintain identical thickness specifications (100.0µin / 2.54µm).

RoHS Compliance Status: 1-103735-9 is RoHS non-compliant, while 6-103735-9 is RoHS Compliant.

REACH Status: 1-103735-9 lists REACH Affected status, while 6-103735-9 lists Vendor Undefined status.

Inventory Availability: 1-103735-9 has 1037 pieces in stock, while 6-103735-9 has 2080 pieces in stock.

These differences do not affect the core electrical or mechanical compatibility of the connectors in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both 1-103735-9 and 6-103735-9 are Active status products from TE Connectivity AMP Connectors and are electrically and mechanically interchangeable for standard applications requiring a 20-position, 0.100" pitch shrouded header connector with through-hole mounting.

Selection based on compliance requirements:

For applications requiring RoHS compliance, 6-103735-9 is the appropriate selection. This part meets RoHS Compliant status and eliminates lead-based solder from the post plating, replacing it with pure tin plating while maintaining identical thickness specifications.

For applications without RoHS compliance mandates, 1-103735-9 remains a valid selection and offers equivalent electrical and mechanical performance.

Both parts maintain identical current ratings (3A), operating temperature ranges (-65°C ~ 105°C), contact finishes on mating surfaces (Gold), material flammability ratings (UL94 V-0), and mechanical dimensions. The post plating material difference (Tin-Lead versus Tin) does not affect connector mating or electrical performance in standard applications.

Frequently Asked Questions (FAQ)

Q: Are 1-103735-9 and 6-103735-9 electrically interchangeable?

A: Yes. Both connectors share identical electrical specifications including 3A current rating, 0.100" (2.54mm) mating pitch, 20-position configuration, gold-plated mating contacts, and operating temperature range of -65°C ~ 105°C.

Q: What is the difference between the post plating materials?

A: 1-103735-9 uses Tin-Lead plating on the solder posts, while 6-103735-9 uses Tin plating. Both maintain identical thickness of 100.0µin (2.54µm). This difference reflects the RoHS compliance status of each part.

Q: Can I use 6-103735-9 as a direct replacement for 1-103735-9?

A: Yes, for applications where RoHS compliance is required or preferred. The mechanical and electrical compatibility is identical. The primary consideration is the post plating material and associated compliance status.

Q: Can I use 1-103735-9 as a direct replacement for 6-103735-9?

A: Substitution is possible from an electrical and mechanical standpoint. However, if the original design specified 6-103735-9 for RoHS compliance, using 1-103735-9 would introduce a non-compliant component into the assembly.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical contact lengths (mating: 0.230", post: 0.130"), overall contact length (0.545"), insulation height (0.535"), and all other mechanical dimensions.

Q: What is the significance of the keying slot feature?

A: Both connectors include a keying slot feature, which provides polarization to prevent incorrect mating orientation. This feature is identical on both 1-103735-9 and 6-103735-9.

Q: Are both parts suitable for automotive applications?

A: Yes. Both 1-103735-9 and 6-103735-9 are rated for automotive applications, along with general purpose, medical, and telecommunications use.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
