8STR-03-006 Equivalent & Substitute Parts

Part Overview

The 8STR-03-006 is a 3-circuit barrier block connector manufactured by TE Connectivity AMP Connectors. This terminal block features a 0.438" (11.12mm) pitch with screws and captive plate termination on the top and solder turret termination on the bottom. The connector is rated for 30A at 600V and accommodates wire gauges from 10-18 AWG. The product is classified as obsolete, making identification of equivalent substitute parts necessary for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8STR-03-006 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Terminal Block Type: Barrier Block
• Number of Circuits: 3
• Number of Wire Entries: 3
• Top Termination: Screws with Captive Plate
• Barrier Type: 3 Wall (Tri)
• Mounting Type: Chassis, Panel

Allowable Parameter Variations: Substitute parts may differ in the following parameters while maintaining functional compatibility:

• Pitch tolerance: ±0.005" (±0.127mm) from 0.438" (11.12mm)
• Current Rating: Equal to or greater than 30A
• Voltage Rating: Equal to or greater than 600V
• Wire Gauge: Capable of accommodating 10-18 AWG minimum
• Operating Temperature Range: Minimum -40°C to 120°C coverage
• Bottom Termination: Alternative solder configurations acceptable

The substitute part YK1110333000G meets the mandatory matching criteria for terminal block type, circuit count, termination style, and barrier configuration. However, this substitute exhibits reduced electrical ratings (20A current, 300V voltage) and narrower wire gauge compatibility (12-22 AWG), which represent functional limitations compared to the original specification.

Engineering Selection Recommendations

8STR-03-006 (Original Part): The 8STR-03-006 is obsolete and no longer manufactured. Existing inventory of 1,165 pieces is available as new original stock. This part is ROHS3 compliant and carries UL94 V-0 flammability certification. The part is suitable for applications requiring 30A at 600V with wire gauges from 10-18 AWG.

YK1110333000G (Substitute Part): The YK1110333000G is an active product from Amphenol Anytek with 688 pieces available as new original stock. This substitute is ROHS3 compliant and carries UL94 V-0 flammability certification, matching the compliance profile of the original part. The substitute features a pitch of 0.433" (11.00mm), which differs by 0.005" from the original 0.438" specification. The substitute is rated for 20A at 300V, representing reduced electrical capacity compared to the original 30A at 600V rating. Wire gauge compatibility is 12-22 AWG, which excludes the 10 AWG capability of the original part. Bottom termination differs from solder turret to solder eyelets. Operating temperature range is -40°C to 115°C, which is 5°C lower than the original specification.

Selection of the substitute part is appropriate only for applications where the reduced current rating (20A maximum), reduced voltage rating (300V maximum), and narrower wire gauge range (12-22 AWG) are compatible with system requirements. The pitch difference of 0.005" must be evaluated for mechanical fit within the target application.

Frequently Asked Questions (FAQ)

Q: Can the YK1110333000G directly replace the 8STR-03-006 in all applications?

A: No. The substitute part has reduced electrical ratings (20A versus 30A current; 300V versus 600V voltage) and narrower wire gauge compatibility (12-22 AWG versus 10-18 AWG). Substitution is only appropriate for applications operating within the lower electrical specifications of the YK1110333000G.

Q: What is the significance of the pitch difference between 0.438" and 0.433"?

A: The pitch difference of 0.005" (0.127mm) affects the physical spacing of the connector terminals. This difference must be evaluated for mechanical compatibility with the target application's PCB layout, panel cutouts, or mounting hardware.

Q: Are both parts RoHS compliant?

A: Yes. Both the 8STR-03-006 and YK1110333000G are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What is the difference between solder turret and solder eyelet terminations?

A: Solder turret termination (8STR-03-006) features a cylindrical post for solder connection. Solder eyelet termination (YK1110333000G) features a ring or eyelet configuration for solder connection. Both are solder-based bottom terminations but differ in physical geometry and solder joint characteristics.

Q: Is the YK1110333000G suitable for high-voltage applications?

A: No. The YK1110333000G is rated for 300V maximum, which is half the voltage rating of the original 8STR-03-006 (600V). Applications requiring 600V operation must use the original part or identify alternative substitutes with matching voltage specifications.

Q: What is the operating temperature difference between the two parts?

A: The 8STR-03-006 operates from -40°C to 120°C, while the YK1110333000G operates from -40°C to 115°C. The substitute has a 5°C lower maximum operating temperature limit.

Q: Can 10 AWG wire be used with the YK1110333000G?

A: No. The YK1110333000G accommodates wire gauges from 12-22 AWG only. The original 8STR-03-006 supports 10-18 AWG, which includes 10 AWG capability not available in the substitute.

Q: What packaging is available for each part?

A: The 8STR-03-006 is available in unspecified packaging with 1,165 pieces in stock. The YK1110333000G is available in bulk packaging with 688 pieces in stock.
