Key Parameters

Substitute Part Grouping Explanation

The 4608X-101-511LF qualifies as a direct substitute based on the following critical parameters:

• Resistance value: 510 Ohm (identical)
• Tolerance: ±2% (identical)
• Number of resistors: 7 (identical)
• Power per element: 200mW (identical)
• Temperature coefficient: ±100ppm/°C (identical)
• Circuit type: Bussed (identical)
• Package / Case: 8-SIP (identical)
• Mounting type: Through Hole (identical)
• Operating temperature range: -55°C ~ 125°C (identical)
• Number of pins: 8 (identical)

Both parts are manufactured by Bourns Inc. and maintain electrical and mechanical compatibility. The primary difference is packaging format (Tube vs. Bulk) and minor dimensional variations within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the 4308R-101-511LF and 4608X-101-511LF are Active products with ROHS3 compliance and identical electrical specifications. Selection between these parts is determined by packaging and inventory requirements rather than functional performance. The 4308R-101-511LF is supplied in Tube packaging, while the 4608X-101-511LF is supplied in Bulk packaging. Dimensional differences are minor and do not affect circuit board layout compatibility for standard through-hole applications. Both parts carry EAR99 export classification and are subject to identical tariff codes.

Frequently Asked Questions (FAQ)

Q: Can the 4608X-101-511LF replace the 4308R-101-511LF in existing designs?

A: Yes. Both parts share identical electrical specifications (510 Ohm, ±2% tolerance, 200mW per element, ±100ppm/°C temperature coefficient) and mechanical compatibility (8-SIP through-hole package). Dimensional variations are within acceptable tolerances for standard PCB layouts.

Q: What is the difference between Tube and Bulk packaging?

A: Tube packaging (4308R-101-511LF) is used for smaller quantity orders and component handling. Bulk packaging (4608X-101-511LF) is used for higher volume procurement. Both formats contain identical components with no functional difference.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, carry EAR99 export classification, and share identical HTSUS tariff codes (8533.21.0050). REACH status differs (4308R is REACH Affected; 4608X is REACH Unaffected), which may impact supply chain documentation requirements depending on end-use jurisdiction.

Q: Do the dimensional differences affect PCB design?

A: The dimensional variations (length: 0.784" vs. 0.798"; width: 0.085" vs. 0.098"; height: 0.195" vs. 0.200") are minor and do not impact standard through-hole PCB layouts. Both parts use identical pin spacing for the 8-SIP package.

Q: What is the resistor matching ratio specification?

A: The resistor matching ratio is not specified in the provided parameters for either part. Refer to manufacturer datasheets for precision matching applications requiring specific ratio tolerances.
