4608X-102-221 Equivalent & Substitute Parts

Part Overview

The Bourns 4608X-102-221 is a 220 Ohm isolated 4-resistor network array in 8-SIP package configuration, rated for 300mW power per element with ±2% tolerance and ±100ppm/°C temperature coefficient. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. Active alternatives from both Bourns and Vishay Dale manufacturers provide functional equivalence with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (220 Ohm), tolerance (±2%), circuit type (Isolated), power rating per element (300mW), pin count (8), package type (8-SIP), and operating temperature range (-55°C ~ 125°C). All identified substitutes maintain these core electrical and mechanical specifications. Secondary parameters including resistor-ratio-drift, physical dimensions, and compliance certifications are documented for design validation but do not disqualify substitution based on functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, 4608X-102-221LF is the primary substitute, offering identical electrical specifications to the obsolete 4608X-102-221 with active product status and ROHS3 compliance. This part maintains the same Bourns 4600X series lineage and packaging.

For applications requiring alternative manufacturer sourcing, 4308R-102-221LF and MSP08A03220RGEJ provide functional equivalence with active status and ROHS3 compliance. The 4308R series from Bourns and MSP series from Vishay Dale both meet all core electrical parameters. Note that 4308R-102-221 and CSC08A03220RGPA are available but carry RoHS non-compliance status.

Physical dimension variations exist across substitute families. The 4308R series measures 0.784" L x 0.085" W (19.91mm x 2.16mm), while CSC and MSP series measure approximately 0.790" L x 0.098" W (20.07mm x 2.49mm). These dimensional differences are within typical through-hole PCB tolerance ranges but should be verified against specific board layout constraints.

Frequently Asked Questions (FAQ)

Q: Can 4608X-102-221LF be used as a direct replacement for 4608X-102-221?

A: Yes. The 4608X-102-221LF maintains identical electrical specifications (220 Ohm, ±2%, 300mW, ±100ppm/°C, 8-SIP) and physical package dimensions. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). Pin configuration and PCB footprint are identical.

Q: What are the key differences between Bourns 4300R and 4600X series substitutes?

A: Both series meet all core electrical requirements. The 4300R series (4308R-102-221, 4308R-102-221LF) exhibits resistor-ratio-drift of 50ppm/°C and slightly smaller physical dimensions (0.784" L x 0.085" W). The 4600X series (4608X-102-221LF) maintains ±100ppm/°C temperature coefficient. Selection depends on application-specific drift tolerance requirements.

Q: Are Vishay Dale substitutes (CSC08A03220RGPA, MSP08A03220RGEJ) electrically equivalent?

A: Yes. Both Vishay Dale parts maintain the same 220 Ohm resistance, ±2% tolerance, 300mW power rating, and ±100ppm/°C temperature coefficient. The MSP08A03220RGEJ carries ROHS3 compliance, while CSC08A03220RGPA does not. Physical dimensions are comparable to the 4600X series.

Q: Do physical dimension differences affect PCB compatibility?

A: Through-hole 8-SIP packages have standardized pin spacing (0.100" pitch). Dimensional variations in length and width (ranging from 0.784" to 0.798" L and 0.085" to 0.098" W) are within typical PCB tolerance ranges. Verify specific board layout constraints if space is critical.

Q: Which substitute offers the best compliance profile?

A: 4608X-102-221LF, 4308R-102-221LF, and MSP08A03220RGEJ all carry ROHS3 compliance and active product status. Selection between these three depends on series preference (Bourns 4600X, Bourns 4300R, or Vishay MSP) and availability requirements.
